A statue of Plancus, the city's founder, in the city hall of Basel, Switzerland.

Augusta Raurica, or Colonia Augusta Rauracorum, was founded by Lucius Munatius Plancus around 44 BC in the vicinity of a local Gallic tribe, the Rauraci, relatives of the Helvetii. No archaeological evidence from this period has yet been found, leading to the conclusion that, either the settlement of the colony was disturbed by the civil war following the death of Julius Caesar, or that Plancus' colony was actually in the area of modern Basel, not Augst.

The inscription on Munatius Plancus' grave merely states the name of the colony as Colonia Raurica. A fragmentary inscription from the Augustinian period speaks of the Colonia P[aterna] (?) M[unatia] (?) [Felix] (?) [Apolli]naris [Augusta E]merita [Raur]ica (letters in brackets are reconstructions). Apart from this fragmentary reference, the first certain witness to the use of the name Augustus comes from the geographer Ptolemy in the Ancient Greek form Augústa Rauríkon (lat. Augusta Rauricorum).

Augusta Raurica played an important role in Augustus' plans of conquest with two other colonies that bear his name: Augusta Praetoria (modern Aosta at the southern end of the Great Saint Bernard Pass) and Augusta Vindelicum (modern Augsburg, an outpost on the Danube). These three Augustae form the corners of a triangle that reaches across the alpine conquests of Augustus, the long base of which form the Rhine knee to the Danube formed the frontier against unconquered Germania.

During excavations it was determined that the city was founded on a high plateau just south of the Rhine river. Two small rivers, the Ergolz and Violen, have carved a triangle in the plateau, the base of which is about 1 kilometer wide along the base of the Jura Mountains, and the apex points northward toward the Rhine, about 1 kilometer from the base. This point is the site of the Roman castrum, or military fortification. The city is, therefore, well-defended by steep slopes to the north, east, and west.

Temple at Augusta Raurica

The next step in planning the city was the surveying of the area according to the architect's plans for the city. Every important public building had its specific place, starting with the temple of Jupiter as the sacred high point from which the street network would spread. The architect, who was responsible for executing the plans for the city, next laid a longitudinal axis across the triangle 36˚ west of north to form the main street of the settlement. Other longitudinal streets were laid out parallel to the main street at intervals of 55 meters. The main street was then divided into sections of 66 meters (255 Roman feet), which formed the corners of 10 crossing streets. This created a series of rectangular blocks of around 50 by 60 meters. The streets were laid on a solid bed of gravel and flanked by gutters on both sides. The more important roads featured covered sidewalks behind rows of columns.

The limits of Colonia Raurica can no longer be determined with absolute accuracy. However the approximate boundaries can be determined by examining the extent of Augst in the Early Middle Ages. This would seem to indicate the colony extended from Basel toward the mouth of the Aare, then up the Aare to the mouth of the Sigger below Solothurn, across to the Lüssel, and then back down the Birs to Basel, though this is still conjecture. New research, based on tiles stamped with the mark of the Vindonissa Legion, indicates some administrative dependence on Vindonissa. This would indicate that the colony reached over the Bözberg toward Frick, with the Thiersteinberg below Frick forming the eastern boundary. The western boundary, was near the mouth of the Birs, possibly marked by a border station. Early Roman cremation remains, found in 1937 by the church in Neuallschwil, show that such a post did exist on the main road north (toward Blotzheim) into Alsace. The Colonia Raurica, on the whole, contained the modern Canton of Basel, the Frick valley, and the eastern Jura Mountains of the Canton of Solothurn. The total area of the colony was around 700 km².

By the 2nd century AD, Augusta Raurica was a prosperous commercial trading centre and, in its glory days, the capital of a local Roman province. It is estimated that the population reached approximately 20,000 people. Augusta Raurica prospered between the 1st and 3rd centuries, and exported smoked pork and bacon to other parts of the Roman Empire. The city possessed the typical amenities of a Roman city, an amphitheatre, a main forum, several smaller forums, an aqueduct, a variety of temples, several public baths and the largest Roman theatre north of the Alps, with 8,000 to 10,000 seats. Many of these sites are open to visitors year-round.

In 250 AD, a powerful earthquake damaged a large part of the city. Shortly after, around 260 AD, Alemanni tribes and/or marauding Roman troops destroyed the city. The Romans attempted to maintain their military position by building a fortress on the Rhine, Castrum Rauracense, the walls of which are still partly intact. Augusta Raurica was resettled on a much smaller scale on the site of the castrum. These two settlements form the centers of the modern communities of Augst and Kaiseraugst.

In 1442, these communities were divided along the Ergolz and Violenbach rivers. The western portion was given to Basel, which became a canton of Switzerland in 1501. In 1833, Augst became part of the Canton of Basel-Land. The eastern part became part of Habsburg territories and, to differentiate between the two towns, was renamed Kaiseraugst. Kaiseraugst became part of Switzerland in 1803 after the defeat of the Habsburgs during the Napoleonic Wars.

Many of the Roman buildings have been discovered and conserved through excavations, and most are open to the public:

Amphitheatre: only modest remains exist.

Aqueduct: supplied Augusta Raurica with drinking water from the Liestal (parts are visible and accessible in Heidenloch in Liestal, as well as northeast of the treatment plant in Füllinsdorf).

Main forum: with the temple of Jupiter, basilica, and the assembly chamber of the town council.

Theater: forms an architectural unit with the temple across the street.

Several private commercial buildings also have been found (a taberna, a bakery, a potter, and a tilekiln), as well as portions of a sewer. Around 80% of the built-up area has yet to be excavated. Augusta Raurica is the best-preserved Roman city north of the Alps that has not been built-over in medieval or modern times.

The Roman Museum houses the most important finds from the Roman city and presents the history of Augusta Raurica. In the museum, visitors will often find special exhibits, as well as most the significant archaeological find at Augusta Raurica: the silver treasure of Kaiseraugst. This treasure hoard was found in the fortress in 1961-1962, and it is presumed to have once been the property of a commander. The museum also has a reconstruction of a Roman house, with artifacts and reconstructions showing daily domestic and commercial life from the Roman period.

Roman theatre (structure)
–
Roman theatres derive from and are part of the overall evolution of earlier Greek theatres. Indeed, much of the influence on the Romans came from the Greeks. However, Roman theatres have specific differences, such as generally being built upon their own instead of earthen works or a hillside. Roman theatres were built in all areas of the empire from Spain to the Middle East, because of the Romans ability to influence local architecture, we see numerous theatres around the world with uniquely Roman attributes. There exist similarities between the theatres and amphitheatres of ancient Rome/Italy and they were constructed out of the same material, Roman concrete, and provided a place for the public to go and see numerous events throughout the Empire. However, they are two different structures, with specific layouts that lend to the different events they held. Amphitheatres did not need superior acoustics, unlike those provided by the structure of a Roman theatre, while amphitheatres would feature races and gladiatorial events, theatres hosted events such as plays, pantomimes, choral events, and orations. Their design, with its form, enhances the natural acoustics. These buildings were semi-circular and possessed certain inherent architectural structures, with minor differences depending on the region in which they were constructed, the scaenae frons was a high back wall of the stage floor, supported by columns. The proscaenium was a wall that supported the front edge of the stage with ornately decorated niches off to the sides, the Hellenistic influence is seen through the use of the proscaenium. The Roman theatre also had a podium, which supported the columns of the scaenae frons. The theatre itself was divided into the stage and the seating section, vomitoria or entrances and exits were made available to the audience. The auditorium, the area in which people gathered, was constructed on a small hill or slope in which stacked seating could be easily made in the tradition of the Greek Theatres. The center of the auditorium was hollowed out of a hill or slope, while the outer radian seats required structural support and this was of course not always the case as Romans tended to build their theatres regardless of the availability of hillsides. All theatres built within the city of Rome were completely man-made without the use of earthworks, the auditorium was not roofed, rather, awnings could be pulled overhead to provide shelter from rain or sunlight. Some Roman theatres, constructed of wood, were torn down after the festival for which they were erected concluded. This practice was due to a moratorium on permanent theatre structures that lasted until 55 BC when the Theatre of Pompey was built with the addition of a temple to avoid the law, some Roman theatres show signs of never having been completed in the first place. Inside Rome, few theatres have survived the centuries following their construction, Theatre of ancient Greece Theatre of ancient Rome Amphitheatre Roman architecture

Basel-Landschaft
–
The canton of Basel-Landschaft, is one of the 26 cantons of Switzerland. It shares borders with the cantons of Basel-Stadt, Solothurn, Jura and Aargau, and with the French région of Alsace, Basel-Landschaft, together with Basel-Stadt, formed the historic Canton of Basel until they separated following the uprising of 1833. In Roman times, the area of Basel was a centre of Roman activity, there are well-preserved remains at the site of Augusta Raurica in the canton of Basel-Landschaft. Around AD200 there were about 20,000 people living in this city, the remains are on display in an open-air museum. The museum attracts over 140,000 visitors per year, many of these visitors are schoolchildren from other parts of Switzerland. The site of Augusta Raurica includes the best-preserved amphitheatre north of the Alps, the lands of the canton Basel-Landschaft are part of the lands acquired by the city of Basel. Until the end of the 16th century, most of the land belonged to the city of Basel. After Napoleon’s visit in 1798, the country achieved equality with the city, the country was economically dependent on the city, most probably because of the low level of education in the agricultural areas at the time. The city of Basel remained the cultural and economic centre of both Basel half cantons until then, castles and residences of Basel merchants dominated much of the landscape in Basel-Landschaft. After 1830 there were political quarrels and armed conflict in the canton of Basel, some of these were concerned with the rights of the population in the agricultural areas. They ultimately led to the separation of the canton Basel-Landschaft from the city of Basel on 26 August 1833, since then, there has been a movement for reunification. This movement gained momentum after 1900 when many parts of Basel-Landschaft became industrialized, the two half cantons agreed in principle to merge, but in 1969 the people of Basel-Landschaft voted down a referendum on this proposal in favour of retaining their independence. It is thought that the economic gap between the two cantons was the main reason why the population changed their attitude. That vote was not the end of a relationship between the two Basels. The two half cantons have since signed a number of agreements to co-operate, the contribution of Basel-Landschaft to the University of Basel since 1976 is just one example. The canton of Basel-Landschaft lies in the north of Switzerland, the Jura mountain chain traverses the canton. The rivers Ergolz and Birs drain the lands of the canton, in 1988 the canton of Basel-Landschaft had this aim written into its constitution. The aim remains to change the Swiss constitution to recognize the two cantons of Basel as full members, ^a FDP before 2009, FDP. The Liberals after 2009 ^b * indicates that the party was not on the ballot in this canton

Switzerland
–
Switzerland, officially the Swiss Confederation, is a federal republic in Europe. It consists of 26 cantons, and the city of Bern is the seat of the federal authorities. The country is situated in western-Central Europe, and is bordered by Italy to the south, France to the west, Germany to the north, and Austria and Liechtenstein to the east. Switzerland is a country geographically divided between the Alps, the Swiss Plateau and the Jura, spanning an area of 41,285 km2. The establishment of the Old Swiss Confederacy dates to the medieval period, resulting from a series of military successes against Austria. Swiss independence from the Holy Roman Empire was formally recognized in the Peace of Westphalia in 1648. The country has a history of armed neutrality going back to the Reformation, it has not been in a state of war internationally since 1815, nevertheless, it pursues an active foreign policy and is frequently involved in peace-building processes around the world. In addition to being the birthplace of the Red Cross, Switzerland is home to international organisations. On the European level, it is a member of the European Free Trade Association. However, it participates in the Schengen Area and the European Single Market through bilateral treaties, spanning the intersection of Germanic and Romance Europe, Switzerland comprises four main linguistic and cultural regions, German, French, Italian and Romansh. Due to its diversity, Switzerland is known by a variety of native names, Schweiz, Suisse, Svizzera. On coins and stamps, Latin is used instead of the four living languages, Switzerland is one of the most developed countries in the world, with the highest nominal wealth per adult and the eighth-highest per capita gross domestic product according to the IMF. Zürich and Geneva have each been ranked among the top cities in the world in terms of quality of life, with the former ranked second globally, according to Mercer. The English name Switzerland is a compound containing Switzer, a term for the Swiss. The English adjective Swiss is a loan from French Suisse, also in use since the 16th century. The name Switzer is from the Alemannic Schwiizer, in origin an inhabitant of Schwyz and its associated territory, the Swiss began to adopt the name for themselves after the Swabian War of 1499, used alongside the term for Confederates, Eidgenossen, used since the 14th century. The data code for Switzerland, CH, is derived from Latin Confoederatio Helvetica. The toponym Schwyz itself was first attested in 972, as Old High German Suittes, ultimately related to swedan ‘to burn’

Roman Republic
–
It was during this period that Romes control expanded from the citys immediate surroundings to hegemony over the entire Mediterranean world. During the first two centuries of its existence, the Roman Republic expanded through a combination of conquest and alliance, by the following century, it included North Africa, most of the Iberian Peninsula, and what is now southern France. Two centuries after that, towards the end of the 1st century BC, it included the rest of modern France, Greece, and much of the eastern Mediterranean. By this time, internal tensions led to a series of wars, culminating with the assassination of Julius Caesar. The exact date of transition can be a matter of interpretation, Roman government was headed by two consuls, elected annually by the citizens and advised by a senate composed of appointed magistrates. Over time, the laws that gave exclusive rights to Romes highest offices were repealed or weakened. The leaders of the Republic developed a tradition and morality requiring public service and patronage in peace and war, making military. Many of Romes legal and legislative structures can still be observed throughout Europe and much of the world in modern nation states, the exact causes and motivations for Romes military conflicts and expansions during the republic are subject to wide debate. While they can be seen as motivated by outright aggression and imperialism and they argue that Romes expansion was driven by short-term defensive and inter-state factors, and the new contingencies that these decisions created. In its early history, as Rome successfully defended itself against foreign threats in central and then northern Italy, with some important exceptions, successful wars in early republican Rome generally led not to annexation or military occupation, but to the restoration of the way things were. But the defeated city would be weakened and thus able to resist Romanizing influences. It was also able to defend itself against its non-Roman enemies. It was, therefore, more likely to seek an alliance of protection with Rome and this growing coalition expanded the potential enemies that Rome might face, and moved Rome closer to confrontation with major powers. The result was more alliance-seeking, on the part of both the Roman confederacy and city-states seeking membership within that confederacy. While there were exceptions to this, it was not until after the Second Punic War that these alliances started to harden into something more like an empire and this shift mainly took place in parts of the west, such as the southern Italian towns that sided with Hannibal. In contrast, Roman expansion into Spain and Gaul occurred as a mix of alliance-seeking, in the 2nd century BC, Roman involvement in the Greek east remained a matter of alliance-seeking, but this time in the face of major powers that could rival Rome. This had some important similarities to the events in Italy centuries earlier, with some major exceptions of outright military rule, the Roman Republic remained an alliance of independent city-states and kingdoms until it transitioned into the Roman Empire. It was not until the time of the Roman Empire that the entire Roman world was organized into provinces under explicit Roman control

Roman Empire
–
Civil wars and executions continued, culminating in the victory of Octavian, Caesars adopted son, over Mark Antony and Cleopatra at the Battle of Actium in 31 BC and the annexation of Egypt. Octavians power was then unassailable and in 27 BC the Roman Senate formally granted him overarching power, the imperial period of Rome lasted approximately 1,500 years compared to the 500 years of the Republican era. The first two centuries of the empires existence were a period of unprecedented political stability and prosperity known as the Pax Romana, following Octavians victory, the size of the empire was dramatically increased. After the assassination of Caligula in 41, the senate briefly considered restoring the republic, under Claudius, the empire invaded Britannia, its first major expansion since Augustus. Vespasian emerged triumphant in 69, establishing the Flavian dynasty, before being succeeded by his son Titus and his short reign was followed by the long reign of his brother Domitian, who was eventually assassinated. The senate then appointed the first of the Five Good Emperors, the empire reached its greatest extent under Trajan, the second in this line. A period of increasing trouble and decline began with the reign of Commodus, Commodus assassination in 192 triggered the Year of the Five Emperors, of which Septimius Severus emerged victorious. The assassination of Alexander Severus in 235 led to the Crisis of the Third Century in which 26 men were declared emperor by the Roman Senate over a time span. It was not until the reign of Diocletian that the empire was fully stabilized with the introduction of the Tetrarchy, which saw four emperors rule the empire at once. This arrangement was unsuccessful, leading to a civil war that was finally ended by Constantine I. Constantine subsequently shifted the capital to Byzantium, which was renamed Constantinople in his honour and it remained the capital of the east until its demise. Constantine also adopted Christianity which later became the state religion of the empire. However, Augustulus was never recognized by his Eastern colleague, and separate rule in the Western part of the empire ceased to exist upon the death of Julius Nepos. The Eastern Roman Empire endured for another millennium, eventually falling to the Ottoman Turks in 1453, the Roman Empire was among the most powerful economic, cultural, political and military forces in the world of its time. It was one of the largest empires in world history, at its height under Trajan, it covered 5 million square kilometres. It held sway over an estimated 70 million people, at that time 21% of the entire population. Throughout the European medieval period, attempts were made to establish successors to the Roman Empire, including the Empire of Romania, a Crusader state. Rome had begun expanding shortly after the founding of the republic in the 6th century BC, then, it was an empire long before it had an emperor

Basel
–
Basel is a city in northwestern Switzerland on the river Rhine. Basel is Switzerlands third-most-populous city with about 175,000 inhabitants, located where the Swiss, French and German borders meet, Basel also has suburbs in France and Germany. In 2014, the Basel agglomeration was the third largest in Switzerland with a population of 537,100 in 74 municipalities in Switzerland, the official language of Basel is German, but the main spoken language is the local variant of the Alemannic Swiss German dialect. Basel has been the seat of a Prince-Bishopric since the 11th century, the city has been a commercial hub and important cultural centre since the Renaissance, and has emerged as a centre for the chemical and pharmaceutical industry in the 20th century. It hosts the oldest university of the Swiss Confederation, There are settlement traces on the Rhine knee from the early La Tène period. The unfortified settlement was abandoned in the 1st century BC in favour of an Oppidum on the site of Basel Minster, probably in reaction to the Roman invasion of Gaul. In Roman Gaul, Augusta Raurica was established some 20 km from Basel as the administrative centre. The city of Basel eventually grew around the castle, the name of Basel is derived from the Roman-era toponym Basilia, first recorded in the 3rd century. It is presumably derived from the personal name Basilius, the Old French form Basle was adopted into English, and developed into the modern French Bâle. The Icelandic name Buslaraborg goes back to the 12th century Leiðarvísir og borgarskipan, Basel was incorporated into Germania Superior in AD83. Roman control over the area deteriorated in 3rd century, and Basel became an outpost of the Provincia Maxima Sequanorum formed by Diocletian, the Alamanni attempted to cross the Rhine several times in the 4th century, but were repelled. In a great invasion of AD406, the Alemanni appear to have crossed the Rhine river a final time, conquering and then settling what is today Alsace, from this time, Basel has been an Alemannic settlement. The Duchy of Alemannia fell under Frankish rule in the 6th century, and by the 7th century, based on the evidence of a third solidus with the inscription Basilia fit, Basel seems to have minted its own coins in the 7th century. Under bishop Haito, the first cathedral was built on the site of the Roman castle, at the partition of the Carolingian Empire, Basel was first given to West Francia, but passed to East Francia with the treaty of Meerssen of 870. The city was plundered and destroyed by a Magyar invasion of 917, the rebuilt city became part of Upper Burgundy, and as such was incorporated into the Holy Roman Empire in 1032. Since the donation by Rudolph III of Burgundy of the Moutier-Grandval Abbey and all its possessions to Bishop Adalbero II in 999 till the Reformation, in 1019, the construction of the cathedral of Basel began under German Emperor Heinrich II. In 1225–1226, the Bridge over the Rhine was constructed by Bishop Heinrich von Thun, the bridge was largely funded by Basels Jewish community which had settled there a century earlier. For many centuries to come Basel possessed the only permanent bridge over the river between Lake Constance and the sea, the Bishop also allowed the furriers to found a guild in 1226

Gauls
–
The Gauls were Celtic peoples inhabiting Gaul in the Iron Age and the Roman period. Their Gaulish language forms the branch of the Continental Celtic languages. The Gauls emerged around the 5th century BC as the bearers of the La Tène culture north of the Alps, Gaul was never united under a single ruler or government, but the Gallic tribes were capable of uniting their forces in large-scale military operations. They reached the peak of their power in the early 3rd century BC, after this, Gaul became a province of the Roman Empire, and the Gauls were culturally assimilated into a Gallo-Roman culture, losing their tribal identities by the end of the 1st century AD. The Gauls of Gallia Celtica according to the testimony of Caesar called themselves Celtae in their own language, the name Gaul itself may be derived from Latin Galli, or it may be derived from the Germanic word Walha. Gaulish culture developed out of the Celtic cultures over the first millennia BC, the Urnfield culture represents the Celts as a distinct cultural branch of the Indo-European-speaking people. The spread of iron working led to the Hallstatt culture in the 8th century BC, the Hallstatt culture evolved into the La Tène culture in around the 5th century BC. The Greek and Etruscan civilizations and colonies began to influence the Gauls especially in the Mediterranean area, Gauls under Brennus invaded Rome circa 390 BC. Following the climate deterioration in the late Nordic Bronze Age, Celtic Gaul was invaded in the 5th century BC by tribes later called Gauls originating in the Rhine valley. Gallic invaders settled the Po Valley in the 4th century BC, defeated Roman forces in a battle under Brennus in 390 BC and raided Italy as far as Sicily. A large number of Gauls served in the armies of Carthage during the Punic Wars, in the Aegean world, an invasion of Eastern Gauls appeared in Thrace, north of Greece, in 281 BC. However, according to the Roman legend of the gold of Delphi. One king Cerethrius invaded the Thracians, while another Gallic king Bolgios invaded Macedonia and Illyria where he killed the Macedonian king Ptolemy Keraunos, in 278 BC Gaulish settlers in the Balkans were invited by Nicomedes I of Bithynia to help him in a dynastic struggle against his brother. They numbered about 10,000 fighting men and about the number of women and children. They were eventually defeated by the Seleucid king Antiochus I, in a battle where the Seleucid war elephants shocked the Galatians. While the momentum of the invasion was broken, the Galatians were by no means exterminated and continued to demand tribute from the Hellenistic states of Anatolia to avoid war,4,000 Galatians were hired as mercenaries by the Ptolemaic Egyptian king Ptolemy II Philadelphus in the 270 BC. According to Pausanias, soon after arrival the Celts plotted “to seize Egypt, ”, Galatians also participated at the victorious in 217 BC Battle of Raphia under Ptolemy IV Philopator, and continued to serve as mercenaries for the Ptolemaic Dynasty until its demise in 30 BC. They sided with the renegade Seleucid prince Antiochus Hierax, who reigned in Asia Minor, after the defeat, the Galatians continued to be a serious threat to the states of Asia Minor

Julius Caesar
–
Gaius Julius Caesar, known as Julius Caesar, was a Roman politician, general, and notable author of Latin prose. He played a role in the events that led to the demise of the Roman Republic. In 60 BC, Caesar, Crassus, and Pompey formed an alliance that dominated Roman politics for several years. Their attempts to power as Populares were opposed by the Optimates within the Roman Senate. Caesars victories in the Gallic Wars, completed by 51 BC, extended Romes territory to the English Channel, Caesar became the first Roman general to cross both the Channel and the Rhine, when he built a bridge across the Rhine and crossed the Channel to invade Britain. These achievements granted him unmatched military power and threatened to eclipse the standing of Pompey, with the Gallic Wars concluded, the Senate ordered Caesar to step down from his military command and return to Rome. Caesar refused the order, and instead marked his defiance in 49 BC by crossing the Rubicon with the 13th Legion, leaving his province, Civil war resulted, and Caesars victory in the war put him in an unrivalled position of power and influence. After assuming control of government, Caesar began a programme of social and governmental reforms and he centralised the bureaucracy of the Republic and was eventually proclaimed dictator in perpetuity, giving him additional authority. But the underlying political conflicts had not been resolved, and on the Ides of March 44 BC, a new series of civil wars broke out, and the constitutional government of the Republic was never fully restored. Caesars adopted heir Octavian, later known as Augustus, rose to power after defeating his opponents in the civil war. Octavian set about solidifying his power, and the era of the Roman Empire began, much of Caesars life is known from his own accounts of his military campaigns, and from other contemporary sources, mainly the letters and speeches of Cicero and the historical writings of Sallust. The later biographies of Caesar by Suetonius and Plutarch are also major sources, Caesar is considered by many historians to be one of the greatest military commanders in history. Caesar was born into a family, the gens Julia. The cognomen Caesar originated, according to Pliny the Elder, with an ancestor who was born by Caesarean section. The Historia Augusta suggests three alternative explanations, that the first Caesar had a head of hair, that he had bright grey eyes. Caesar issued coins featuring images of elephants, suggesting that he favored this interpretation of his name, despite their ancient pedigree, the Julii Caesares were not especially politically influential, although they had enjoyed some revival of their political fortunes in the early 1st century BC. Caesars father, also called Gaius Julius Caesar, governed the province of Asia and his mother, Aurelia Cotta, came from an influential family. Little is recorded of Caesars childhood, in 85 BC, Caesars father died suddenly, so Caesar was the head of the family at 16

Dendrochronology
–
Dendrochronology is the scientific method of dating tree rings to the exact year they were formed in order to analyze atmospheric conditions during different periods in history. Dendrochronology is useful for determining the timing of events and rates of change in the environment and also in works of art and architecture, such as old panel paintings on wood, buildings and it is also used in radiocarbon dating to calibrate radiocarbon ages. New growth in trees occurs in a layer of cells near the bark, a trees growth rate changes in a predictable pattern throughout the year in response to seasonal climate changes, resulting in visible growth rings. Each ring marks a complete cycle of seasons, or one year, as of 2013, the oldest tree-ring measurements in the Northern Hemisphere extend back 13,900 years. Dendrochronology derives from Ancient Greek, δένδρον, meaning tree limb, χρόνος, meaning time, and -λογία, the Greek botanist Theophrastus first mentioned that the wood of trees has rings. In his Trattato della Pittura, Leonardo da Vinci was the first person to mention that trees form rings annually, in 1737, French investigators Henri-Louis Duhamel du Monceau and Georges-Louis Leclerc de Buffon examined the effect of growing conditions on the shape of tree rings. They found that in 1709, a severe winter produced a distinctly dark tree ring, the English polymath Charles Babbage proposed using dendrochronology to date the remains of trees in peat bogs or even in geological strata. During the latter half of the century, the scientific study of tree rings. In 1859, the German-American Jacob Kuechler used crossdating to examine oaks in order to study the record of climate in western Texas, in 1866, the German botanist, entomologist, and forester Julius Ratzeburg observed the effects on tree rings of defoliation caused by insect infestations. By 1882, this observation was already appearing in forestry textbooks, in the 1870s, the Dutch astronomer Jacobus C. Kapteyn was using crossdating to reconstruct the climates of the Netherlands, in 1881, the Swiss-Austrian forester Arthur von Seckendorff-Gudent was using crossdating. From 1869 to 1901, Robert Hartig, a German professor of forest pathology, wrote a series of papers on the anatomy, in 1892, the Russian physicist Fedor Nikiforovich Shvedov wrote that he had used patterns found in tree rings to predict droughts in 1882 and 1891. During the first half of the 20th century, the astronomer A. E. Douglass founded the Laboratory of Tree-Ring Research at the University of Arizona. Growth rings, also referred to as tree rings or annual rings, growth rings are the result of new growth in the vascular cambium, a layer of cells near the bark that is classified as a lateral meristem, this growth in diameter is known as secondary growth. Visible rings result from the change in speed through the seasons of the year, thus, critical for the title method. If the bark of the tree has been removed in a particular area, the rings are more visible in temperate zones, where the seasons differ more markedly. The inner portion of a ring is formed early in the growing season, when growth is comparatively rapid and is known as early wood. Many trees in temperate zones make one growth ring each year, hence, for the entire period of a trees life, a year-by-year record or ring pattern is formed that reflects the age of the tree and the climatic conditions in which the tree grew

Dendrochronology (or tree-ring dating) is the scientific method of dating tree rings (also called growth rings) to the …

Drill for dendrochronology sampling and growth ring counting

The growth rings of a tree at Bristol Zoo, England. Each ring represents one year; the outside rings, near the bark, are the youngest.

Diagram of secondary growth in a tree showing idealised vertical and horizontal sections. A new layer of wood is added in each growing season, thickening the stem, existing branches and roots, to form a growth ring.

Hospice at the Great St Bernard, with Roman road in foreground. The modern road is below it. To the right the snowy slope descends to the tarn. On the other side of the monastery buildings the road descends into Switzerland.

Bust of Plancus symbolising Roman philosophy. The bust has been said to show evidence of hemiplegia. Found in 1823 near the Jardin des Plantes and the amphitheatre of Lyon. On display at the Gallo-Roman Museum of Lyon.
